Are the tools really free?

Yes — all core PDF and AI tools are free to use. Some heavy conversion actions may require a free account.

Is there a file size limit?

Individual uploads can be up to 100 MB. Use Split PDF to handle larger files.

Do you add watermarks to the output?

No. Output files are clean, no watermarks added.

Files are processed to produce your output and can be deleted immediately. They are never used to train AI models.

Best Free Online PDF Tools (2026)

The PDF is 30+ years old and still the format of record. Yet most people still juggle five separate websites to convert one, merge two, or compress a third. It's absurd — and expensive when those sites charge per file.

NovaDocs AI puts every essential PDF tool in one workspace, and every core action is free. Here's the map.

Convert to and from PDF

PDF to Word — high-fidelity DOCX with headings, tables and images preserved
PDF to Excel — extract tables into real spreadsheet cells
PDF to PowerPoint — one slide per page, editable
PDF to Image — export pages as JPG or PNG
PDF to Text — clean UTF-8, no garbage characters
Word to PDF — pixel-accurate output from DOCX
Excel to PDF — spreadsheets exported with correct page breaks
PowerPoint to PDF — decks converted with fonts and colors intact
Image to PDF — combine multiple images into one PDF

Organize and edit

Merge PDF — combine multiple PDFs into one
Split PDF — pull out specific pages or ranges
Extract Pages — save selected pages as a new PDF
Remove Pages — delete pages permanently

AI-powered PDF tools

This is where NovaDocs AI pulls ahead of every legacy PDF site:

AI Summarizer — chapter-by-chapter recaps
Chat with PDF — ask questions and get grounded answers
AI Translator — 100+ languages, layout preserved
OCR — turn scans into editable text
AI Study Assistant — quizzes, flashcards and notes from any PDF

Why one workspace beats a browser full of tabs

One upload works across every tool — no re-uploading
Batch actions: merge then compress then sign in one flow
Consistent quality — same PDF engine everywhere
Privacy — files processed once, not shipped to five sites

I used to bookmark five PDF sites. Now I just use NovaDocs AI for everything.

Works on any device

NovaDocs AI runs in the browser — no installs, no desktop app. Every tool works on phone, tablet and desktop. Uploads use HTTPS, and all processing is done on encrypted infrastructure.
